1-1/2 inch Copper DWV 90 Degree Street Elbow Copper x Fitting

1-1/2 inch Copper DWV 90° Street Elbow – Copper x Street Copper

The 1-1/2 inch Copper DWV 90 Degree Street Elbow is designed for use in non-pressurized drain, waste, and vent (DWV) systems. This elbow enables a 90-degree change in direction with one male (street) end and one female (cup) end, reducing the need for additional couplings and streamlining pipe layout in horizontal or vertical stacks.

Material and Compliance

• ✅ Material: Wrought copper conforming to ASTM B75/B88 standards
• ✅ Application: Drainage, waste, and vent systems under atmospheric pressure
• ✅ Lead-Free: Complies with lead-free regulations for use in potable and non-potable systems
• ✅ Standards: Manufactured to ASME B16.29 for DWV fittings

Installation Guidance

Installation requires standard copper joining practices including cleaning, fluxing, and soldering. The street-end design allows for direct insertion into the hub of another fitting, simplifying directional transitions and minimizing space constraints in framed walls or chase runs.

• ✔ Use lead-free solder for code compliance
• ✔ Recommended for gravity-flow systems only
• ✔ Avoid pressurized service

Technical Specifications

• Nominal Size: 1-1/2 inch
• Connection: Copper Cup x Street (Spigot) End
• Bend Angle: 90 degrees
• Pressure Rating: Not for use in pressurized systems

Common Applications

This DWV elbow is typically used in residential and light commercial systems for vent stack offsets, horizontal to vertical transitions, and navigating around obstructions in floor or wall cavities. It is well suited for new construction, remodels, and code-compliant retrofits.

Industry Insight

DWV street elbows are favored for their ability to reduce joint count and streamline fittings in compact areas. When installed per local plumbing codes, copper DWV fittings provide decades of reliable service with minimal maintenance.

Specifying the 1-1/2 inch Copper DWV 90° Street Elbow means aligning with proven trade standards for longevity, workability, and code conformity in DWV construction. An essential fitting for efficient layout and secure transitions in any copper waste or vent system.
